However, gonadotropin treatment decreases embryo Clinical Theriogenology • Volume 12 Number 1 • March 202023 viability, based on embryo collection studies.17 Similar to multiple injections of FSH, a single injection of equine chorionic gonadotropin (eCG) increases ovulation rate,18,19 but appears to decrease embryo viability.20 It is noteworthy that anestrous ewes treated with progesterone ovulate when they are also treated with gonadotropins or exposed to rams, but not after progesterone treatment alone.21 P.G. 600® (Intervet/Merck Animal Health, Madison, NJ) is approved for estrus induction in swine.	cache/ct-9197.pdf	txt/ct-9197.txt
